[822173, 1146846] Broken layout on JBossAS7 resource configuration page
Work done for Bug 1144459 was unknowingly trying to fix the problem
reported in Bug 822173.  It succeeded in fixing the column header issue
but caused the regression reported in Bug 1146846.  This (finally) seems
to have fixed the problems for all three BZs, working around the Smartgwt
bug at the root of all of the problems.
